I am planning to use ArgoUMl with AmdroMDA to generate as much of a Jetspeed Portal as possible.

One of the issues that I think will come up in using Jetspeed is the need/ability to break down a fairly big application into a set of JSR-168 portlets.This implies, I think, that I am going to have a number of AndroMDA projects in ArgoUML ; one for each Portlet since each Portlet is an independent object that is loaded into the Jetspeed Portal depending on the user profile, etc.

I think that this is going to result in the same basic entities (employee, business unit, code tables, etc.) appearing in many ArgoUML models.

It seems to make sense to define and maintain these entities in one place and import them into each model in much the same way that the basic AndroMDA entities are incorporated into the model at the start of a AndroMDA project.

Is there some way to do this, using ArgoUML, so that changes to the core entities can be easily replicated to all of the portlet models without having to go to each model and manually change each class in the core that has changed. The work is one issue; the probability of forgetting to make a change or making an error in making the changes in one portlet model is pretty high and will be hard to find when different portlets handle the same entity differently.

Suggestions about how the core entities should be organized to make portlet modelling easier would be appreciated.

Ideally I think that I would like to be able to export part (or all) of a master model of classes and import them into other models overwriting any existing instances of the same entity.
